Just knocked a quick script up to read in an excellon drill file and display it using pygoocanvas:

The lines show the path in the file. Tool changes aren’t yet shown.

Source coming later. After sleep.

   Good work! What’s going on with the line of small holes near the top left? No connecting paths.

   That looks pretty well optimised.

   Source for this would be great if you still have it…

   Hi John,

   After a fair amount of searching, I found the source :-)

   This source comes with no guarantees, and you’ll probably want to remove the pygene references. When I was writing it, I was interested in how much the tool paths could be optimised.

   I’ve put it up in a tarball here.
